View SamplesArnica m. effects were associated with a purported anti-inflammatory and tissue healing actions after trauma, bruises, or tissue injuries, but its cellular and molecular mechanisms are largely unknown. Here Arnica m. dilutions were tested using an in vitro model of macrophages polarized towards a “wound-healing” phenotype. The monocyte-macrophage human THP-1 cell line was cultured and differentiated with phorbol-myristate acetate and Interleukin-4, then exposed for 24 h to Arnica m. centesimal (c) dilutions 2c, 3c, 5c,9c, 15c or Control. None of these treatments affected cell viability. A total of 20 genes were differentially expressed comparing cells treated with Arnica m. 2c with those treated with Control only. Of these, 7 genes were up-regulated and 13 were down-regulated. Functional gene enrichment analysis showed that the most significantly upregulated function concerned 4 genes with a conserved site of EGF-like region (p<0.001) and three genes of proteinaceous extracellular matrix, including heparin sulphate proteoglycan 2 (HSPG2), fibrillin 2 (FBN2), and fibronectin (FN1) (p <0.01). Protein assay in supernatants confirmed a statistically significant increase of fibronectin production in Arnica m. 2c treated cells (p<0.05). Pooled extracts of cells treated with increasing dilutions of Arnica m. (3c, 5c, 15c) showed up-regulation of the same group of genes although with lower effect size. The down-regulated transcripts derive from mitochondrial genes coding for some components of electron transport chain. These findings provide new insights into the action of Arnica m. in tissue healing and repair, identifying increased fibronectin production by macrophages as a major therapeutic target. Overall design: Expression analysis of differentiated THP-1 cell line exposed at Arnica m. centesimal (c) dilution 2c, plus control non-exposed line both in 5 replicates.

View SamplesExtremely variable clinic and genetic features characterize Mitochondrial Encephalomyopathy Disorders (MED). Pathogenic mitochondrial DNA (mtDNA) defects can be divided into large-scale rearrangements and single point mutations. Clinical manifestations become evident when a threshold percentage of the total mtDNA is mutated. In some MED, the "mutant load" in an affected tissue is directly related to the severity of the phenotype. However, the clinical phenotype is not simply a direct consequence of the relative abundance of mutated mtDNA. Other factors, such as nuclear background, can contribute to the disease process, resulting in a wide range of phenotypes caused by the same mutation. Using Affymetrix oligonucleotide cDNA microarrays (HG-U133A), we studied the gene expression profile of muscle tissue biopsies obtained from 12 MED patients (4 common 4977-bp deleted mtDNA and 8 A3243G: 4 PEO and 4 MELAS phenotypes) compared with age-matched healthy individuals.

View SamplesPlant organs are comprised of distinct cell types with unique assemblages of mRNAs. This is a collection of CEL files of mRNA profiles of the total steady-state mRNAs and polysomal mRNAs of distinct cell types of the whole root and shoot of 7-d-old Arabidopsis thaliana seedlings. The cell type specific mRNA populations are those present in ribosome-mRNA complexes. This sub-population of mRNAs was obtained by first establishing a collection of Arabidopsis lines that express a FLAG-epitope tagged ribosomal protein L18 (RPL18) directed by promoters expressed in specific cell types and regions. Thirteen different promoter:FLAG-RPL18 lines were used. The targeted cell types and promoters included root atrichoblast (non-hair) epidermal cells (pGL2), root endodermis (pSCR), root stelar xylem and pericycle (pWOL, pSHR), root phloem companion cells (phloem CC) (pSUC2, pSultr2;2), root proliferating cells (pRPL11C), root cortex meristematic cells (pCO2), root cortex elongation/maturation cells (pPEP), shoot mesophyll (pRBCS), shoot epidermis (pCER5), shoot guard cells (pKAT1), shoot bundle sheath (pSultr2;2), shoot phloem CC (pSUC2) and shoot trichomes (pGL2). A CaMV 35S promoter:FLAG-RPL18 line was used to obtain the polysomal mRNA of multiple cell types. The immunopurification of ribosome-mRNA complexes of specific cell types/regions was accomplished by the method described in Zanetti et al. (Plant Physiology, 138, 624-635; 2005). Hybridization of the immunopurified mRNAs to the Affymetrix ATH1 DNA microarray platform and subsequent data analysis permitted the identification of transcripts that are enriched or depleted in specific cell types/regions of roots and shoots. The dataset includes samples from cell types/regions from seedlings grown under control conditions and cell types/regions of seedlings exposed to low oxygen stress (hypoxia) for 2 h.

View SamplesThis study examined the small antral follicles (SAFs) in ovaries of young adult rhesus monkeys following consumption of a western-style diet (WSD), with or without chronically elevated androgen levels since before puberty. Cholesterol or testosterone (T; n=6/group) implants were placed subcutaneously beginning at 1 yr of age, with addition of a WSD (high fat/fructose) at 5.5 yrs. Ovaries from treated females and age-matched controls were collected at 7 yrs of age. Compared to controls, consumption of a WSD, with and without T treatment, increased the numbers of SAFs per ovary (P<0.001), due to the presence of more atretic follicles (P<0.01). Immunostaining for the cellular proliferation markers (pRb and pH3) was greater in granulosa cells of healthy SAFs (P<0.01), while staining for the cell cycle inhibitor (p21) was higher in atretic SAFs (P<0.01). Intense CYP17A1 staining was observed on the theca of SAFs from WSD+/- T groups, compared to controls. Microarray analyses of the transcriptome in SAFs isolated from a subgroup (n=3/grp) of WSD and WSD+T treated females and controls consuming a standard diet, identified mRNA levels for 1944 genes changed >2-fold (p<0.05) among the three groups. Pathway analyses identified several gene pathways altered by WSD and/or WSD+T associated with lipid, carbohydrate and lipid metabolism, plus ovarian processes. Alterations of several SAF mRNAs are similar to those observed in follicular cells from women with PCOS. These data indicate chronic exposure to a WSD in the presence and absence of chronically elevated T alters structure and function of SAFs within primate ovaries.

View SamplesTo determine the impact of ?Np63a knockdown on steady-state mRNA levels, we performed poly(A)-enriched RNA-seq analysis of lung squamous cell carcinoma line H226 (inducible shControl and shp63) in the presence of 1µg/mL doxycycline to induce shRNA expression. Overall design: Poly(A)+ RNA for two independent biological replicates was purified from H226 cells (inducible shControl and shp63) incubated treated for six days with 1 µg/mL doxycycline. a TruSeq Stranded mRNA Library Prep Kit (Illumina). Libraries were sequenced on an Illumina HiSeq 2000 system at the University of Colorado Cancer Center Genomics and Microarray Core facility. Reads were aligned (TopHat2) to the Human reference genome (GRCh37/hg19) and gene-level counts (HTseq-count) were used for differential expression analysis (DESeq2).
